Described interface is made up of pipe joint and locking nut, there is boss the pipe joint below, there is the external screw thread that cooperates with locking nut the top, have the hole of passing through for pipe joint boss upper section on the cover plate assembly, the pipe joint below is connected with the cooling device port, be provided with sealing ring between boss and the cover plate assembly, pipe joint is fixed on the cover plate assembly by locking nut.Adopt this interface to be convenient to being connected and sealing between cooling device and the cover plate assembly, capacitor is easy to assembly quick.
In order to improve cooling effect, described cooling device is arranged on the gap location of capacitor core group both sides metal spraying face and housing.Because the heat that produces during capacitor work is mainly at the metal spraying face, being provided with so effectively in time to derive heat, the cooling effectiveness height.
Described cooling device is made by a metal heat-conducting pipe coiling, and the cooling device body that is arranged on capacitor core group both sides metal spraying face links to each other by the changeover portion body that is arranged on the capacitor core group top; Inner walls is provided with the hook that cooperates with capacitor core group top cooling device changeover portion body.This structure makes cooling device install in capacitor easily.
Be arranged on the cooling device body of capacitor core group both sides metal spraying face and be fixed with the conducting strip that be arranged in parallel with capacitor core group metal spraying face respectively.By enlarging heat-conducting area, improve the heat radiation cooling effect.
As shown from the above technical solution, the utility model can effectively in time be derived the heat in the capacitor by cooling device is set in capacitor, the cooling effectiveness height, can improve the capacitor working temperature upper limit, strengthen the overcurrent capability of capacitor, prolong the useful life of capacitor; Because water cooling efficient height, most of heat is taken capacitor out of by cooling water, and the heat that distributes with thermal-radiating form reduces, thereby can dwindle the volume of capacitor, reduces the manufacturing cost of capacitor.
